AUTOMOBILE HEADLIGHT.

Application flled April 24, 1926. Serial No. 104,344.

This invention relates to automobile headlights. j

An object of the invention is to provide a headlight devoid of imparting laring rays, and yet one which will fully light a road in an eflicient manner.

Another object of the invention is to provide an automobile headlight so constructed as to utilize rays from a parabolic reflector l0 projected to light a road without the use of lenses or shields, or other devices of such a nature commonl employed to reflect, focus and cut off the light rays not employed to light the road. x A further object of my invention is to provide a headlight which has the advantage of directly focusing the light rays upon the road,'a headlight which is highly eflicient in operation, yet of marked simplicity as a whole and in respect to each of its component parts, that its manufacture may be economically facilitated both as regards to parts and their assembly.

With these and other' objects in view which may be incident to my improvements,

the invention consists in the parts and combinations to be hereinafter set forth and claimed.

In order to make my invention more 80 clearly understood, I have shown in the acc'ompanying drawings means for carrying the same into practical efi'ect, without limitin the, improvements intheir useful apphcations to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings forming a part ofthis specification: Figure 1 is a side elevation of my 49 proved automobile headlight, and

Figure 2 is a sectional view of Figure 1 taken through the center. Referring bynumerals to the drawings, 1 represents a cylindrical section having formed upon one end-thereof and integral therewith a conical shaped housing 2. The housing 2 is rovided with a-circular flange or collar 3, t e object of which will hereinafter appear.

socket 4. The socket 4 is mounted in the section 1 with one of its ends projecting Mounted in the cylindrical section 1 is a is a reflector 7. The reflector 7 is fitted tightly upon the socket l and is of such configuration as to fit snugly back of the lamp bulb. The edge of the reflector is provided with a flange 8 which bears against and is flush with the edge of the flange 3, the purpose of which Wlll hereinafter appear.

A circular diaphragm 9 having a central aperture 10 and a sleeve or collar 11 bears against the flange 8 upon the reflector 7. The sleeve 11 on the diaphragm fits snugly over the flange 3 and is secured thereto by means of screws 12. Thus the reflector is supported in a rigid position by binding the rim or flange 8 between the edge of the flange 3 and the diaphragm 9. The periphery of the diaphragm is provided with a threaded portion 13, the purpose of which will hereinafter appear, and the aperture 10 in the diaphragm is so located as to form between its Wall and the flange 8 a shoulder 14.

Mounted upon the threaded portion 13 on the periphery of the diaphragm 9 is a housing 15. The housing 15 may be of any desirable design, however, the form shown which is substantially elliptical is preferred. The housing 15 is open at its endopposite its mounting, and threaded or otherwise secured in the open end of the housing is a sleeve 16 having a flange 17 so formed as to provide an aperture 18 of the same diameter as the aperture 10.

The apertures 10 and 18 are in alignment,

and mounted therein is a cylindrical section nection with the reflector 7 The other end of the cylindrical section 19 projects through 17. Bearing against the flange 17 and the .the aperture 18, and is flush with the flange end of the cylindrical Section 19 are felt washers 20. The washers 20 provide a seat for the glass 21 which is held in position by a sleeve or collar 22 mounted in the ,sleeve 16, and secured in position by screws 23 or any other desirable means.

v the shell or casing in alignment with the re flector; thus the lamp which is mounted centrally with respect to the reflector is in alignment with the axis of the cylinder. It will thus be evident that the utilization of light rays coming from the reflector and the projection thereof in such a manner as to eliminate glare is accomplished.

While I have shown and described the pge ferred embodiment of my invention, I wish it to be understood thatI do not confine my self to the precise details of construction herein set forth, by way of illustration, as

it is apparent that many changesand variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: t

1. An automobile headlight comprising a casing, a support mounted in the casing, the support having a housing integral therewith, a rim upon the housing, a parabolic reflector mounted upon the rim within the housing, a diaphragm mounted upon the rim, the diaphragm clamping the reflector to the housing, a cylindrical member mounted at one end in the diaphragm, the cylindrical member bearing against the reflector and means forsupporting the other end "of the cylindrical member Within the casing.

2. An automobile headlight comprising a casing. a support mounted no one end of the casing, a housing integral with the support, a flanged rim upon the housing, a reflector mounted in the housing, the reflector oearm against the rim of the housing, a diaphragm mounted on the rim, the diaphragm clamping the reflector to the housing, a cylindrical'member. one endof the cylindrical member mountedin the diaphragm, the cylindrical member bearing against the reflector and means within the casing for supporting the other end of the cylindrical member. In testimony whereof I afix my signature.
